7a+21=56
Begin by subtracting 21 on both sides:
21-21=0 so the 21 in the left cancels, then 56-21=35
Your new equation will be
7a=35
Finally, divide by 7 on both sides:
7/7=1 and 35/7=5
your answer will be
a=5
Answer:
8(5) + 8(25) + 8(125) + 8(625) +8(3125)= 10(3125 - 1)=31240
Hence proved Conjecture is correct
L.H.S=R.H.S
Step-by-step explanation:
Consider the pattern:
8(5)=10(5-1)=40
8(5) + 8(25) = 10(25 - 1) =240
8(5) + 8(25) + 8(125) = 10(125 - 1) =1240
8(5) + 8(25) + 8(125) + 8(625) = 10(625 - 1)=6240
According to inductive reasoning next term of pattern will become:
8(5) + 8(25) + 8(125) + 8(625) +8(3125)= 10(3125 - 1)=31240
Checking whether conjecture is correct or not:
Consider L.H.S:
8(5) + 8(25) + 8(125) + 8(625) +8(3125)
40+200+1000+5000+25000
31240
R.H.S:
31240
Hence proved Conjecture is correct
L.H.S=R.H.S
5.6x10^-3 yd/year in feet per day.
There are 3 feet in a yard
(5.6x10^-3)x3=1.68x10^-2 feet/year
Let's take there to be 365 days in the year (Fun fact: The actual duration of our year is <span>365 days 5 hours, 48 minutes 46 seconds)
</span>

<span>
Therefore the correct answer is D.</span>
Answer:Roxana hourly paid is $12
Step-by-step explanation:
overtime pay=p
normal hourly rate=r
p=1.5r
72/4=18
p=$18/hr
p=1.5r
18/1.5 =1.5r /1.5
12=r
